HCE, or Human-Computer Interaction, refers to the study and design of how people interact with computers and technology. It focuses on improving the usability and user experience of software and hardware, ensuring that technology is accessible and efficient for users. This field combines elements from computer science, cognitive psychology, and design to create intuitive interfaces. Researchers in HCE analyze user behavior and preferences to develop better systems. They conduct usability testing and gather feedback to refine products. The ultimate goal of HCE is to create technology that enhances productivity and satisfaction, making it easier for users to achieve their objectives with minimal frustration.
